Pay someone to sharpen them for petes sake. I can't fathom why you would suggest that seemingly off hand, secondary to throwing away and buying new knives.
Because people refuse to sharpen their knifes, no matter what you do. So it's better for them to throw away old blunt knifes and buy new ones. That they will do. And buy a real cutting board at the same time.
